Seismic metamaterial structure with chirality
The invention discloses a seismic metamaterial structure with chirality, which comprises a cylindrical steel core, a middle rubber connecting piece, an external annular cylinder, a square block, a cuboid rubber block, a square tube and soil, and is characterized in that the cylindrical steel core is wrapped in the middle rubber connecting piece, and the middle rubber connecting piece is sleeved in the external annular cylinder; a gap is formed between the middle rubber connecting piece and the outer annular column body, the lower end of the outer annular column body is inserted into the middle of the square block, the square block is fixed to the upper portion of the square cylinder, and the cuboid rubber blocks with the same height as the square block are pasted to the middle axes of the four side faces of the square block. And the square cylinder is buried in soil. The structure has good control and attenuation effects on seismic surface waves, the special property provides excellent vibration and impact absorption capacity for the material, and external impact or vibration borne by the structure is effectively relieved.
本发明公开了一种具有手性的地震超材料结构，包括圆柱钢芯、中间橡胶连接件、外部圆环形柱体、正方形块、长方体橡胶块、方筒、土壤，所述圆柱钢芯包裹在所述中间橡胶连接件内部，所述中间橡胶连接件套设在所述外部圆环形柱体内部，所述中间橡胶连接件与所述外部圆环形柱体之间设有空隙，所述外部圆环形柱体下端插入所述正方形块中部，所述正方形块固定在所述方筒上方，所述正方形块的四个侧面的中轴处粘贴与其等高的所述长方体橡胶块，所述方筒埋入土壤中。本发明中的结构对地震表面波有良好控制和衰减作用，这种特殊的性质为材料提供了卓越的振动和冲击吸收能力，有效减轻结构受到的外部冲击或振动。
